RAIL SUPPORT.

Application filed August 1, 1927.

This invention relates to certain new and useful improvements in composite railroad stringers and more particularly to cross ties of the non-insulated type which areto be em bedded in the concrete of a street or road and in which the rail is supported at substantially the same level as the street or road,

The main object of the invention is to provide a simple, durable and efficient ra l support which is made of fewparts, which are readily assembled and disassembled and which iswell adapted for quantity production at comparatively low cost,

Another object of the inventlon is to provide a generally improved cross tie construction which may be firmly embedded in the concrete and which will not become loosened or broken as a result of heavy loads passing over the rails. i

A further object of the invention is to provide a cross tie construction in which the tops of the rail supporting beams are given a slight inclination whereby the rails slope inwardly slightly in order to conform to the.

-' contour of the wheels.

Further and more limited objects of the in vention will appear as the description proceeds and by reference to the accompany ng drawing in which Fig. 1 is a top plan view of my skeleton frame assembled; Fig. 2 is a vertical sectional view of the completed cross tie with the rails secured in place; Fig. 3 is a vertical sectional view on the line 3--3 of Fig. 1; Fig. 4 is a vertical sectional View on the line 4-4 of Fig. 1; and Fig. 5 is an enlarged fragmentary detail vertical sectional view illustrating the manner of securing the rails in place.

Referring now to the drawings, the reference characters I and 2 designate hollow, spaced, parallel steel beams which are shaped in section as shown most clearly in Fig. 2 and connected by angular cross bars 3 and 4. The cross bars 3 and 4 are bent upwardly slightly at the ends as shown at 5. 6, 7 and 8, the purpose of which will hereinafter appear. The beams 1 and 2 embody sides 9 and 10 and top walls 11. clined in opposite directions as shown in Fig. 2 and. the flanges 9 are slightly longer than the flanges 10 whereby the top portions or walls 11 of each beam are given a slight inclination or slope of about 1" in 25". The side flanges 9 and 10 preferably have portions 12 cut therefrom and bent outwardly as shown and the top portions or walls 11 The flanges 9 and 10 are in- Serial No. 209,779.

preferably have portions 13 cut and bent downwardly therefrom as shown, the purpose of which will also hereinafter appear. The beams 1 and 2 have a pair of oppositely disposed angular slots adjacent each end thereof through which the angular cross bars 3 and 4 extend. The cross bars 3 and 4 have in each end thereof a pair of spaced rectangular openings 15, 16 and 17, 18, res 'iectively. The inclination. of the ends of the cross bars 3 and 4 is such as to allow for the slope of the top walls 11 and the ends of the cross bars lie immediately below and in contact with the under side of the top walls 11. This construction serves to strengthen the beams 1 and 2 at these points. The interiors of the beams 1 and 2 are preferably filled with concrete before the same are brought to the track although this may be done at the track side if desired. The bent portions or projections 12 and 13 on the interior of the beams are firmly embedded in the concrete and serve to strengthen the entire structure. Angular bars are placed in the openings or slots in the ends of the beams when the concrete is ploured so that the concrete will not fill the s ots. v

The road bed is prepared in the usual manner and the ballast B is packed and tamped in the usual way. The beams 1 and 2 are placed in the position shown in Fig. 2 with the bottoms oft-he beams level. The cross bars 3 and 4 are then inserted through the slots in the ends of the beams. The rails 19 are then laid on the tops of the beams as shown in Fig. 2. The sloping top walls of the beams give the rails the proper inclination so that the same will. conform to the contour of the wheel. It will be seen by an inspection of Fig. 2 that the bottom of the rail is the same width as the top wall 11 of the beam. The rails aresec-ured in place by clamps 20 and 21 of a well known type and which form no part of this invention. The clamps 20 and 21 rest on the tops of the cross bars 3 and 4 on opposite sides of the rail and are clamped in place by nuts 22 and 23 which are threaded over the upper ends of bolts 24. and 25. The openings 15, 16 and 17, 18 are so positioned with respect to the cross bars 3 and 4 as to properly position the beams 1 and 2 for the particular gauge track on which the cross tie is to be used. After the rails are secured in place the cross bars 3 and 4 are preferably spot Welded to the beams 1 and 2 so that the beams are held in spaced parallel relation.

The cross tie is now completely assembled. Concrete is now poured in to fill the space between and around the rails up to the levels shown in dot-and-dash linesin Fig. 2. The bent out portions or projections 13 are. firmly engaged and embedded in the concrete. and

serve to tie in the whole construction with the pavement. This construction produces a very durable and eflicient rail support which is capable of withstanding the shocks and vibrations of heavily loaded cars. It isnnderstood that arious changes may be made in the details of my construction and the method of assembly without departing from the spirit of my invention and I therefore wish my invention to be limited only in accordance with the scope of the appended claims.

In some cases where the upper portion of the road bed is to be made of macadam, stone or other material, the space between the rails is only partially filled with concrete, leaving a considerable portion of the rail extending above the level of concrete. The shape of the beams and the bent-out portions 12 serve to firmly anchor the beams in place in the concrete.

In some cases it has been found desirable to omit the bent out projections 12 and 13 and to form the bealns 1 and 2 with a plain or smooth surface. Beams constructed in this manner have been found to give very satisfactory results and an advantage of this construction is that the same are better adapted for shipping as the beams may be nested one within the other thereby saving space and freight charges.

It will nowbe clear that I have provided a cross tie construction which will accomplish the objects of the invention as hereinbefore stated.

Having thus described my invention, what I claim is:---

i l. A rail support ofthe class described embodying a. pair of hollow. parallel metallic beams.-cach of said beams having slots therein adjacent theends thereof, cross bars ertcnding through; said slots and holding said beams in spaced relation, clamping members secured tosaid beams and cross bars and serving also to clamp a rail to each of said beams and concrete filling said beams and the space between said rails.

2. A rail support as set forth in claim 1 in which said beams-are provided with reinforcing members bent outwardly therefrom and embedded in the concrete and serving to reinforce the construction as a whole and to hold said beams against displacement.

3. A rail support of the character set forth comprising a pair of reinforced concrete beams extending parallel with the track, the top. of each beam sloping inwardly and the sides of eachbcam being inclined, each of said beams having slots in the opposite ends thereof, cross bars connecting said pair of beams and extending through said slots, clamping members secured to said beams and cross bars and serving to clamp a rail to each of said beams and concrete disposed between andadjacent each of said beams and serving to hold the same against displacement.

4:. A rail support of the character set forth comprisinga pair of reinforced concrete beams spaced apart and extending alongcach rail, the side walls of each beam being inclined in opposite directions, each of said beams having slots in the opposite ends thereof, cross bars connecting said pair of beams and extending through said slots. lumping members secured to said beams and crossbars and serving to clamp a rail to each of said beams, concrete filling the space adjacent said beams and holding the same against displacement.

(3. A rail support as set forth in claim 4 in which the inclined side walls of said beams have portions cut out and bent outwardly therefrom and embedded in the concrete whereby to reinforce the construction as a whole and to;hold said beams against displacement.
